Sept. 30, 1930. B. R; SCHNEIDER STRIP CONTAINER FOR COILED SPRINGS Filed July 24; 1929 Patented Sept. 30, 1930 UNITED STATES PATENT OFFICE BERNARD R. SCHNEIDER, or nYivD uRsr, NEW-JERSEY, ASSIGNOR T EBCO MACHINE CORPORATION, or NEW YORK, n. Y., A conronnrron on NEW YORK STRIP CONTAINER FOR COILED SPRINGS .Application filed July 24', 1929. Serial .No. 380,688.-

This invention relates to stripzcontainer for colled springs.

An object of the inventionis to providea container or covering instrip form for enclosing and retaining metallic coiled springs, of muslin, cloth or other suitable fabric and the like, doubled along its length or woven or sewed or otherwise secured at one longitudinal edge to give two plies or layers, which are securedtogethertransverse to the direction of length of the strip at regular intervals, to. form pockets into which the springs are inserted and retained; Thesecurement of the' two plies or'layers transverse of the direction of length of the strip to formthe pockets, is preferably had by weaving in the making of the strip material, or by sewing or the like, such transverse securement beginning at the doubled edge and extending but partially for the transverse widthtowardthe openedges of the plies or layers, that is to say, at the mouths of the respective pockets, thusproviding for terminal portions at the free edges of the plies or layers which areentirely unstitched at such open edges for the length of the strip.

As is set forth in the co-pending application Ser. No. 863,869, filed May'17, 1929, by Karl Kaiser and myself, relating to a machine for inserting and enclosing metallic coiled:

springs into the pockets of the strip covering, the free edges of the plies or layers at the termini of the transverse I securements provide an unobstructed passage from mouth to mouth of the successive pockets of the strip container, thus rendering possible the use of a machine devised by said Kaiser and myself having a suitable carrier for feeding coiled springs successively into the respective pockets.

Upon lodgment of the springs in the pockets, the free edges of the strip are stitched or otherwise secured to one another to effectiv-ely enclose the springs individually in the respective pockets.

The strip, of contained coiled springs is employed in the manufacture of mattressing and upholstering, and the like.

Further features and objects of the invention will be more fully understood from the following detail description of the accompanying drawings, in which i 1 Fig.1 is a detail top plan view of a con tainer strip pursuant to my. invention, in which helical springs are enclosed in the re spective pockets; p V Fig. 2 is a sectional elevation on line 2--2 of Fig. l, the springs being displaced ninety degrees in the respective pockets;

Fig. 3 is a sectional elevation on line.3-.3 OfFig-Q;

Fig. 4 is a detail top perspective view of a strip container prior to insertion of the springs;

Fig. 5 is a'detail top plan view of the free terminal portion of a transverse weaving, on a greatly enlarged-scale; and

V Fig. 6 is a sectional elevation on line 66 of Fig. 5.. V i

Referring to Figs. 4, 5 and 6, the strip 10 of muslin, cloth or other suitable fabric or the like is doubled-over upon itself, or sewed or woven to provide an upper .ply orlayer- 12andj a lower'ply or layer 13. r The doubledover or sewed or woven edge 11 may be in the form of closer weavings, reinforced weaving or inter-selvaged portion, connecting the body portions of two strips, as is illustrated in the drawings, the inter-selvaged portion providing for enhanced strength of the material. Pockets for the respective springs are formed successively lengthwise of the strip by any suitable means such as-the weavings 14, stitches or the like, each transverse securement extending from a location 15 to a location 16, the distance between the locations 15, 16, being less than the transversedimensionor width of the strip 10, thereby providing for theregions 17 between the. location 16 and the free edges 18 of theupper and lower plies or layers 12, .13, which are unobstructed by such transverse secureinent,

pockets 20 upon delivering from our machine, the stitchings 21 being applied at the theretofore free edges of the plies or layers 12, 13, the stitehings being made by a sewing machine or by other mechanical or manual sewing operation, or by any other suitable fastening or like means.

\Vhereas there is described in our aforesaid application, a wholly automatic device for feeding coiled or helical springs to a carrier for .receiving and inserting a coil in each pocket successively and withdrawing from each pocket upon insertion of the spring therein, and further including automatic means for holding the springs after insertion in compressed status to enable or facilitate the stitching or other securement at theopen mouths at the free edges of the plies or layers, it will be understood that my invention is also applicable for use with a spring car rier member or the like which may be supplied with springs by manual operation, or the springs inserted in the respective parts manually by any suitable carrier or by wholly manual operation, the free and unobstructed inter-mouth passages enabling the transit from mouth to mouth to be effected without obstruction by any weavings, stitchings, and without requiring the free edges of the layers or plies to be opened up or maintained in opened position by mechanical devices or manual operation.

Usually, and' as is illustrated in Fig. 1 of the drawingsthe dimension between successive transverse securements 14, 14, is less than the width of the strip container material, and the springs 19 are displaced manually or mechanically about an angular movement of ninety degrees within the respective pockets, to locate the axes of the springs 19 in the direction of greater dimension in the respective pockets.

Preferably, the muslin or other fabric is woven as a doubled-up strip and to have a doubled inter-selvaged portion at the edge 11, and the transverse securements 14 may be attained by weaving for the locations of the transverse seeurements for the dimension from the location 15 to the location 16, such weaving being illustrated as to one manner thereof by interweaving alternate weft threads 22 of the lower ply or layer 13, with the weft threads 23 and warp threads 24 of the upper ply or layer 12, the warp threads 25 of the lower ply or weave 13 extending intermediate such interwoven weavings and the alternate weft threads 26 of the lower ply or weave 13. However, any other procedure of weaving or sewing or folding over of a single woven material may be used.

Pursuant to my invention as above set forth, and as illustrated in the drawings, the transverse securements effect engagement of the upper and lower plies at the locations of the securement. Furthermore, the securements are arranged substantially parallel to one another and substantially at right angles to the direction of length of the plies. By such construction, the mouths of the respective pockets are disposed at one and the same lateral side of the plies, thereby facilitating the operations of insertion of the respective coil springs within the pockets and the stitchings or other securement in closing the mouths of the pockets.

lVhereas, I have described my invention by reference to specific forms thereof, it will be understood that many changes and modifications may be made without departing from the spirit ofthe invention.

I claim 1. A strip for containing springs, comprising two layers secured to one another at one longitudinal edge, and means securing said layers in substantial engagement with each other at intervals to provide pockets between the layers to receive springs, the securing means extending substantially parallel to one another and terminating a definite spacing from the free edges of the layers to provide a clearance from pocket to pocket.

2. A strip for containing springs, said strip being doubled lengthwise to'bring opposite lon itudinal edges into proximity and form two layers, the strip having substantially parallel means to secure the layers together in substantial engagement with one another at uniform intervals to form pockets with open mouths adjacent said edges, said means extending across the strip substantially at right angles to the direction of length of the strip and terminating short of said edges.

3. A strip for containing springs comprising two layers secured at one longitudinal edge, and means securing said layers in substantial engagement with one another at substantially uniform intervals to provide pockets between the layers to receive springs, said securing means extending substantially at right angles to said longitudinal edge and from said longitudinal edge continuously to a location spaced from the opposite longitudinal free edges of the layers to provide a clearance from pocket to pocket.

In testimony whereof I have signed this specification this 17th day of July, 1929.

BERNARD R. SCHNEIDER.
